GUS-QS8B-01-1021-C Description

The GUS-QS8B-01-1021-C from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package integrates 15 resistors, each with a 1.02KΩ resistance and an exceptional ±0.25% tolerance, ensuring reliable performance in precision circuits. With a ±100ppm/°C temperature coefficient, it maintains stability across a wide operating range of 70°C to 125°C, derated for optimal power handling. The 0.75W (3/4W) total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for high-density designs requiring robust thermal management. Its gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration, while the compact 4.9mm × 6.02mm × 1.47mm footprint saves board space.
